Application filed March 8,1907. Serial No. 361,243.

To all whom it may concern:

Be it known that I, AARON SCHWARTZ, a citizen of the United States of America, and a resident of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Apparatus for Unloading Vessels, of which the following is a specification.

This invention relates to movable carriers for sand, coal, and similar material and especially to such carriers as barges, scows, etc.

The special object of the present invention is to provide ready means of rapidly unloading the material from the barge or scow, dispensing as far as possible with manual labor and the laborious lifting usually attending the unloading.

The invention consists in providing a carrier with a plurality of bins having valved openings at the bottom through which the material in each row of bins may be discharged upon a movable conveyer, the various conveyers converging at a desired point and delivering the material thereon to a single conveyer mounted upon a boom adapted to extend beyond the limits of the carrier at any desired angle.

The invention further consists of certain novel features of construction and arrangement of parts which will be readily understood by reference to the description of the drawings and to the claims hereinafter given.

Of the drawings: Figure 1 represents a plan of a barge embodying the features of this invention. Fig. 2 represents a vertical section of the same on line 22 on Fig. 1. Fig. 3 represents a plan of the turn-table upon which the boom and discharge belt conveyer is mounted. Fig. 4 represents an elevation of the same. Fig. 5 represents a section on line 5-5 on Fig. 4, looking in the direction of the arrow. Fig. 6 represents an elevation of the end of the boom, and Fig. 7 represents agtransverse section on line 77 on Fig. 6.

Similar characters designate like parts throughout the several figiues of the drawings.

In the drawings, 10 represents a barge of any wellknown construction provided with a plurality of bins lllthe walls of which are inclined and converge at a discharge outlet 12. This outlet 12 is closed by means ofzany suitable valve 13 shown in the present application as a revoluble bladed member driven in any suitablezmanner when it is desired to discharge the mate rial from the bins 11 and which is adapted to close the outlet 12 when at rest.

When the bladed members 13 are revolved to permit the material in the bins 11 to pass through the outlet 12 this material will fall upon an endless belt conveyer 14 mounted upon suitable rollers 15. In the preferred construction the barge is provided with several rows of bins extending longitudinally of the barge,

the discharge outlets 12 therefrom being in parallellines and each row of bins discharging upon a separate belt conveyer 14. Each of the belt conveyers 14 delivers the material thereon to an inclined belt conveyer 16. The outer ends of these conv eyers 16 converge and deliver the material therefrom into a hopper 17 provided with an outlet 18 delivering the material passing therethrough to an endless belt conveyor 19 mounted upon suitable drums 20 and 21 revoluble in suitable bearings on a boom 22. This boom 22 is pivotally mounted upon the shaft 23 having bearings in the vertical plates 24 secured to the circular plate 25 mounted upon a plurality of balls or other friction members 26. The anti-friction members 26 move in any suitable path provided for them in a stationary plate 27 and the circular plate 25 may be readily moved upon said anti-friction members about its axis to move the boom 22 to any desired horizontal angle.

The boomr22 may be elevated to any desired vertical angle by means of the rope 28 passing over a pulley 29 secured to a frame 30 and operated by means of a Windlass 31 of any well-known construction. The drum 20 for driving the belt conveyer 19 is itself driven by means of the gear 32 meshing with an intermediate gear 33 which in turn meshes with a gear 34 mounted upon the end of a shaft 35, the other end of which has secured thereto a bevel gear 36. This gear 36 meshes with a similar bevel gear 37 mounted 'upon the upper end of a vertical shaft 38 extending through the center of the revoluble plate 25 and having secured to its opposite end a gear 39 which is driven bya gear 40.0n a shaft 41. This shaft 41 has mounted thereon a pulley 42 which is driven by a belt 43 from any suitable motor 44. This motor 44 also is connected to the other belt conveyers 14 and 16 to move them when it is desired to unload the barge. The drum 21 at the outer end of the boom 22 is mounted upon a shaft 45 having a bearing in a box 46 which is adjustable lengthwise of said boom by means of the screws 47 for the purpose of taking up the slack in the belt conveyer 19 all in an obvious manner. An additional means for taking up the slack in the belt conveyer 19 is provided by means of a roller 48 mounted in bearings in the boxes 49 adjustable by means of the screws 50 in slots in the vertical plates 24. This roller bears against the under side of the belt conveyer l9 and by adjusting the box 49 the belt may be operated upon to Wrap it more firmly around the drum 20 in order to drive the conveyer belt 19 thereby to better advantage.

In the operation of the invention the bins 11 are filled with sand, coal, or similar material. The barge horizontal angle to discharge the load at the particular point selected, the movement of the boom in a horizontal direction being accomplished by means of the turn-table 2527 while the angle of elevation of said boom is changed by means of the Windlass 31. When this has been accomplished the motor 44 is set in motion and all of the conveyer belts 14, 1G, and 19 are operated thereby while at the same time the bladed valve members 13 are revolved and the sand or other contents of the bins is permitted to pass through the outlet 12 up onto the conveyer 14 on which it is carried in the direction of the arrows on said belts and delivered onto the inclined belt 16 which throws the material into the hopper 17 from which it passes on to the conveyer belt 19 which finally discharges it beyond the limits of the carrier onto a wharf or any other selected point. This provides a ready means of handling loads of this kind, insuring a very rapid unloading without manual labor, the whole load being automatically discharged by means of the motor 44 which may be of any Well-known construction. The details of construction of the various elements may be varied to suit various conditions without affecting the principles of this invention.

It is believed that from the foregoing description the operation of the invention and the many advantages of a construction of this class will be fully apparent.
